Exposure and Development Adjustments for
Long and Short Exposures
At the exposure times in the table below, compensate for the
reciprocity characteristics of this film by increasing exposure
and adjusting the development as shown.
It may be difficult to use the table to estimate the adjusted
times for calculated exposure times between 1 and 100
seconds. The graphs below will help you find the adjusted
times for calculated exposure times between those given in
the table.

DARKROOM RECOMMENDATIONS
Use a safelight equipped with a KODAK 1A Safelight Filter
(light red) with a 15-watt bulb. Keep the safelight at least
4 feet (1.2 metres) from the film. Run tests to determine that
safelight use gives acceptable results for your application.
For information on safelight testing, see KODAK
Publication K-4, How Safe Is Your Safelight?
PROCESSING
Small-Tank Processing (8- or 16-ounce tank)
Develop EKTAGRAPHIC HC Slide Film at 68°F (20°C) in
a small tank. We recommend using KODAK Developer
D-11 or KODAK PROFESSIONAL KODALITH Super RT
Developer for processing this film. KODAK Developer D-11
provides slightly lower contrast, more exposure latitude,
longer solution life, and high projection contrast. It also
produces faster film speed or short camera exposures.
Note: For even development of the entire roll, first fill the
tank with developer. Then, using the above safelight
handling instructions, drop the loaded film reel into the
developer and attach the top to the tank. Firmly tap the tank
on the top of the work surface to dislodge any air bubbles.
Agitate for 5 seconds every 30 seconds throughout
development. You can do the remaining operation in room
light.
